# I have a query form that performs a complex SQL query based on form params and then creates a bunch of @user\_x collections for display purposes. However, AJAX is bombing out with what seems to be a simple error. When I submit the form, instead of replacing the desired partial (under the form) it displays:
# try { Element.update("CONTENTS OF PARTIAL SNIPPED);’); throw e }
The partial correctly updates but something small is wrong preventing
the in-place update.
FORM VIEW
\<%= javascript\_include\_tag :defaults %\>
\<% form\_for :query, :url =\> {:action =\> :query\_results} do |f| %\>
FORM CONTENTS SNIPPED
\<% form\_remote\_tag :url =\> {:action =\> :query\_results} do %\>
\<%= submit\_tag “Query” %\>
\<% end %\>
\<% end %\>
ACTION
def query\_results
@conditions = conditionalize(params[:query])
@users = User.find(:all, :conditions =\> @conditions)
respond\_to { |format| format.js }
end
QUERY\_RESULTS.JS.RJS
page.replace\_html(“query\_results”, :partial =\> “query\_results”)

Forgot an important part!
FORM VIEW (below form)
\<% if @users %\>
